The property is underlain by Upper Triassic Vancouver Group, Karmutsen Formation, basaltic to andesitic flows with intercalations of felsic ashflow tuffs. The volcanics are interbedded with lenses of Triassic to Jurassic Kunga Group limestone and minor argillite. A granodiorite to tonalitic pluton, probably related to the Middle Jurassic San Christoval Plutonic Suite, lies to the south.

The prominent structural feature is an east-west trending fault. Two distinct foliations strike northwest, dipping south and north-south, dipping east. Minor northeast trending faults occur on the south part of the property.

Gold mineralization, associated with pyrite and arsenopyrite, occurs in variably silicified and epidote-chlorite altered felsic to mafic volcanics. Gold is also localized in brecciated quartz veins and minor calcite-quartz veins cutting the volcanics. The mineralization also occurs in narrow (20-60 centimetres) silicified brecciated zones at the limestone-volcanic contacts, of which one sample assayed 4.53 grams per tonne gold. Subsequent drilling intersected a 1.51 metre silicified shear zone with 6.5 grams per tonne gold (Assessment Report 9458).

Bateaux Resources drilled two diamond drill holes totaling 121.9 metres in 1989.
